"It can be said that since the day the first set of global positioning system was established, we have been facing such risks.
After all, these satellites were artificially launched into outer space, and our current understanding of outer space is not as thorough as we imagined. It can even be said that we only have a smattering of knowledge.
The satellites in the network face a variety of dangers.
There are deliberate attacks by hostile forces, as well as more and more frequent launch missions by various countries, and various other factors.
For example, there are now nearly a million satellites carrying out various missions gathered in various orbits of the earth's outer space.
Although the first satellite has its own orbit, trajectory, speed, and so on, no one can guarantee that there are no satellites deliberately launched by hostile forces to target a certain party.
Moreover, these nearly a million satellites operating in outer space at the same time. On the one hand, it is too crowded, and on the other hand, because there are too many of them, it affects the signal transmission accuracy of some positioning satellites.
This is the same reason why there are too many people in a city. When there are too many people, it is inevitable that it will be crowded and collide with each other, and it is easy to affect the vision of others. Today's positioning satellites are also facing the same problem.
Of course, this is only a man-made factor, and it is also the influence of non-man-made factors.
For example, meteorites, meteors, solar magnetic explosions, unknown space rays, and so on in outer space will cause unpredictable effects on positioning satellites!
But these are unavoidable factors. Even if we know, with our current technological means, there is no better solution! "
The twins used the simplest language to explain to Elder Xu. They tried their best to make Elder Xu understand what they meant.
Although Elder Xu was not an expert in this area, he also understood what the twins meant.
That was to say, what Chen Qiang said just now was indeed true.
Of course, in terms of man-made factors, in order to ensure their people's livelihood and national defense, countries would try their best to avoid deliberately causing friction before they had a better solution.
But what about the non-man-made factors?
According to Chen Qiang's knowledge, when the earth entered the recovery of spirit qi, there was a long period of empty space on earth.
This was because in the process of the Blood Demon escaping to the Shengmo Dalu, he inadvertently brought a huge amount of spirit qi to earth, but at the same time, almost all kinds of satellites in outer space were destroyed!
Of course, Chen Qiang would not say this explicitly, but the non-man-made factors mentioned by the twins just now actually included this situation.
"As the two of you have just said, there are certain flaws and hidden dangers in the satellite positioning system.
However, the communication bracelet in our hands right now is a receiver for a different kind of positioning system.
As for the specifics of this kind of positioning system, I don't know much about it, but I've heard a little about how it works.
As you said just now, relying on satellites as the signal source of the positioning system is precisely because the Earth is a sphere. In this way, the signals emitted by the networked satellites can form a cross point, and then constitute the positioning function.
However, the signal source of the communication bracelet's positioning system was hidden deep in the sea.
Furthermore, the signal emitters placed in the sea emitted waves that were accompanied by ultra-sonic waves!
This was because there were countless creatures in the ocean, and the ultra-infrasound sound waves would naturally cause the creatures in the ocean to feel a sense of fear.
Of course, in reality, ultra-infrasound waves were indeed destructive to the creatures in the sea. Therefore, there was no need to worry about the signal emitters in the sea being destroyed. Moreover, the depth of the emitters only needed to be one kilometer.
On the one hand, the sea area on Earth was vast, so it was not easy to be discovered. On the other hand, because it was at such a depth, it would not be discovered by enemy forces. This prevented the possibility of man-made destruction.
Of course, as for the non-human factors mentioned by the two of you just now, it was even more unlikely to happen.
In addition, because of the medium, the power and intensity of the signal emitted in the sea are not as accurate as in outer space. I think this is also a problem, right?
After all, different mediums have refractive index and penetrating power to be considered. Therefore, the technician who invented this positioning system used a miniature nuclear fission device as the energy source, and the emitted signal was an ultra-short frequency band ∑ ray.
Since ∑ rays had the shortest frequency range, coupled with the fact that the emission frequency had reached a relatively high level, it formed an effect similar to a one-inch punch. Layers of signals were emitted into the air, forming an intersection with other signals, and thus had the function of positioning.
This is the basic principle of the positioning system of the communication bracelet in our hands. Of course, I don't know the specifics. "
While Chen Qiang said these words, the twin brothers had been listening carefully and recording at the same time.
After all, the idea of the positioning system mentioned by Chen Qiang was proposed as early as a few decades ago, but it couldn't solve some specific problems.
For example, the factors that Chen Qiang mentioned just now, such as the seawater medium, refraction, the characteristics of the Earth's sphere, the energy source, and so on.
Of course, there was one point that Chen Qiang didn't mention, and that was the materials.
"Brother Chen Qiang, I roughly understand what you said just now. Moreover, it's not a problem to create a miniature energy source now, but the materials to create a signal source …"
Chen Qiang stopped him in time. "As far as I know, this is not a problem. I remember that just four years ago, our country discovered a new type of high-density nano-level composite material. It is most suitable as a signal source, and it can also prevent instantaneous high-intensity stamping. A signal source made of this material can be guaranteed to last for at least a few hundred years, right?
And the most important point is that if this positioning system is successfully developed, it can eliminate the step of the transfer station. It can be directly received by this kind of communication bracelet and automatically located.
Of course, as for this point, you will have to go back and disassemble the communication bracelet to study it. "
On this point, Chen Qiang was still a little conservative.
Because the communication bracelet on his hand was an example.
After the signal source that provided the signal transfer was developed, it had never been changed.
After Chen Qiang finished speaking, one of the young men's eyes suddenly lit up.
"Brother, you're talking about the QC483 composite material, right? I remember that this is a material that is between a liquid and a solid state. It is now widely used in individual protective equipment in various countries.
But I never thought that this material could be used as a signal source! "
Chen Qiang smiled when he heard this. "This is easy to understand. After all, the problem that we faced in developing the positioning system in the deep sea was not just the material. It's normal that we didn't think of it. "
